Purpose of Hot Blast Smoke Exhausters GD-25

Centrifugal single-inlet hot blast smoke exhausters GD-25 are designed for recirculating flue gases from boilers using solid and gas-oil fuels with various steam capacities. It is also allowed to use GD-25 exhausters for extracting hot and dusty flue gases from furnaces of technological lines for the production of iron ore pellets in the ferrous metallurgy industry (sintering plants) with gas dust concentration up to 0,5 g/nm³ and dust particle size not more than 0.5 μ.

Operating Conditions of Hot Blast Smoke Exhausters GD-25

The exhauster is designed for continuous operation indoors and outdoors in moderate and tropical climate conditions (climatic versions U or T, placement category 1, DSTU 15150-69). Startup is allowed at a temperature in the scroll casing not lower than -30 °C. The maximum permissible temperature at the exhauster inlet must not exceed 400 °C. Operation is allowed at a rotational speed of 1000 rpm.
